dc.description.abstract	Let Mn be the C∗ algebra of n × n complex matrices and let ϕ : Mn → Mn be a completely positive map. Suppose A ∈ Mn is a self-adoint matrix. We prove a submajorization result concerning positive and negative parts of the spectrum of ϕ(A). As a consequence, we obtain inequalities concerning the smallest and the largest eigenvalues of the Schur product of A and B, where A and B are self-adjoint.	en_US
